Build model: As glamorous as this might sound, this might just be executing a few lines of code like “reg = LinearRegression().fit(X, y)”.

Generate test design: Pending your modeling approach, you might need to split the data into training, test, and validation sets.

Select modeling techniques: Determine which algorithms to try (e.g.

Here you’ll likely build and assess various models based on several different modeling techniques. To understand CRISP-DM in greater detail and assess whether and how you should apply it, explore the Data Science Team Lead course and organizational consulting services.

Even teams that don’t explicitly follow CRISP-DM, can still use the framework diagram to explain how the differences between data science and software projects. Published in 1999 to standardize data mining processes across industries, it has since become the most common methodology for data mining, analytics, and data science projects.ĭata science teams that combine a loose implementation of CRISP-DM with overarching team-based agile project management approaches will likely see the best results.

Deployment – How do stakeholders access the results?.

Evaluation – Which model best meets the business objectives?.

Modeling – What modeling techniques should we apply?.

Data preparation – How do we organize the data for modeling?.

Data understanding – What data do we have / need? Is it clean?.

Business understanding – What does the business need?.

It’s like a set of guardrails to help you plan, organize, and implement your data science (or machine learning) project. The CRoss Industry Standard Process for Data Mining ( CRISP-DM) is a process model with six phases that naturally describes the data science life cycle.
